ABSTRACT:
The ceiling fan has a motor and a removable switch unit. The motor comprises an inner stator, an outer rotor, a rotor casing rotatable with the rotor, and a tubular boss which depends from the stator and through which first wiring extends. The switch unit comprises a housing, switchgear for the motor contained in the housing, and second wiring connected to the switchgear. The first and second wiring have complementary electrical connectors which are able to pass through an aperture provided in the upper end of the housing and the housing has connecting means at its upper end for connecting the housing to the depending boss. The connecting means is in the form of an openable or enlargeable clamp to allow the connectors to be passed through the aperture and the first wiring to extend through and be withdrawn from the clamp.
